Arrangement of efficient energy-saving supply and exhaust single-room ventilation in flats, houses, cottages, social and commercial premises. Heat recovery minimises ventilation heat losses.

Humidity balance and controllable air exchange create individually set microclimate.
High-tech ceramic energy accumulator with heat recovery up to 85 %. Due to its cellular structure it has a larger contact area surface and high efficiency. The energy accumulator is featured with excellent heatconducting properties and thermal energy storage capacity.
Warm stale air is extracted from the premise, flows through the ceramic regenerator and transfers a part of the accumulated heat and moisture to it. As the ceramic regenerator gets warmed up, the unit switches to the supply mode.

Clean cold intake air flows through the regenerator and absorbs accumulated heat and humidity.When the ceramic regenerator is cooled down, the unit is switched to the extract air mode.
The unit operation mode control is performed by means of manual three-position switches located on the unit casing or using the remote controller.The unit is equipped with a humidity sensor for indoor humidity control and regulation.
Remote control and operation mode selection:
The unit is designed for external through-the-wall installation inside a prepared round hole in the outer wall of the building.The best ventilation solution is pairwise installation of reverse phase connected units. Some units supply fresh air to the room and the other units extract stale air from the room. This allows to arrange the most efficient balanced ventilation. In case of brand new construction the units are mounted in two stages:
  • pre-installation at the stage of the indoor finishing and outer decorative wall finishing. It includes installation of the telescopic air ducts, outer ventilation hood and laying out of electric cables.
  • final mounting before commissioning of a house. It includes installation of the regenerator, the filters, connection of the ventilation unit.

If mounting of the ventilation hood on the outer wall is undesirable it may be flush mounted and the external grille may be inserted into the outer window jamb using the KIT BlauPlast 204x60-2 pre-installation kit. Available upon separate order.
